Yes, Akira, this site 'Exotica' i a good one and seem to be very interesting.
I will look this week more in details when i have more time.
For now i must work on my hd workbench (i am checking (for corrupt disk) and defrag a lot of Amiga disk
It is a surprise why disks are not automatically defragmented after the final version.
One of the Workbench system disk is at 67% fragmanted...
Aie, aie, aie this is not good
